Question

# Which of the following relations is not correct?

A
G=HTS
B
ΔGsystem=ΔHsystemTΔSsystem
C
TΔSsystem=ΔHsystemΔGsystem
D
ΔHsystem=ΔGsystem+TΔSsystem

Solution

## The correct option is A $$\Delta G_{system} = \Delta H _{system} T \Delta S_{system}$$$$G$$=$$H - TS$$$$\Rightarrow \Delta G_{system}=\Delta H_{system}-T\Delta S_{system}$$$$\Rightarrow T\Delta S_{system}=\Delta H_{system}-\Delta G_{system}$$$$\Rightarrow \Delta H_{system}=\Delta G_{system}+T\Delta S_{system}$$Thus, option $$B$$ is not correct relation.Hence, the correct option is $$B$$Chemistry
